Do CPU‑Intensive Tasks Block Node.js? An Experimental Study of libuv Thread Pool

An experiment demonstrates that CPU‑intensive encryption tasks do not block Node.js when the number of concurrent tasks does not exceed libuv’s default four‑thread pool, but adding a fifth task causes blocking, illustrating how libuv’s thread pool size and environment variable UV_THREADPOOL_SIZE affect concurrency.
